Abstract
A web wrap apparatus is provided having a separator with a separating edge and a feeder transporting web to a bale chamber.

Claims19
A web wrap apparatus for use in a baler, said baler having a pick-up mechanism for delivering material to a bale chamber in which the material delivered to the bale chamber is wrapped with a web material, the web wrap apparatus comprising:
- an actuator mechanism;
- a feeder moved by the actuator mechanism between retracted and feed positions, the feeder having a carrier configured to clamp against opposite sides of the web material to carry the web material with respect to the bale chamber;
- a separator having a separator edge, the separator being movable with respect to the feeder such that a tip of the separator edge can be brought into engagement with the web material carried by the carrier to sever the web material;
- and
- a stripper mounted to the carrier and configured to engage the separator edge during movement of the feeder between the retracted and feed positions;
- wherein, when the feeder is moved in a first direction between the retracted and feed positions, the stripper engages the tip of the separator edge and a slanted surface terminating in the tip, and, when the feeder is moved in a second, opposite direction between the retracted and feed positions, the stripper engages the tip of the separator edge and a side of the separator edge opposite the slanted surface.
A baler, comprising:
- a bale chamber;
- a pick-up mechanism for delivering material to the bale chamber;
- a supply of web material;
- a web wrap apparatus configured to wrap the material delivered to the bale chamber with the web material, the web wrap apparatus comprising:
- an actuator mechanism;
- a feeder moved by the actuator mechanism between retracted and feed positions, the feeder having a carrier configured to clamp against opposite sides of the web material and carry the web material with respect to the bale chamber;
- a separator having a separator edge, the separator being movable with respect to the feeder such that a tip of the separator edge can be brought into engagement with the web material carried by the carrier to sever the web material;
- and
- a stripper mounted to the carrier and configured to engage the separator edge during movement of the feeder between the retracted and feed positions;
- wherein, when the feeder is moved in a first direction between the retracted and feed positions, the stripper engages the tip of the separator edge and a slanted surface terminating in the tip, and, when the feeder is moved in a second, opposite direction between the retracted and feed positions, the stripper engages the tip of the separator edge and a side of the separator edge opposite the slanted surface.
